This subscription box is intended for kids between six and 12 years old, with projects that are accessible for even the newest beginner. Kids will be able to try all kinds of Javascript coding projects, from making video games to building their own working apps. A Grownup Guide and email support can give kids a little extra help as needed, and are especially useful if parents are new to coding too. Boxes are delivered monthly, and each one builds on the previous one to foster continued education and encourage more complex coding and app-building. The package has received high marks from parents, with a 4.5-star average rating.

Note that this promotional price is for the first month only. After that, the monthly cost will go back up to $30, so you’ll need to cancel your subscription if you don’t want to pay the full price.
